When you set the number of traces, that setting determines the upper limit trace number; for example, if the setting is 3, traces 1 through 3 will be displayed. To set the number of traces, use the following command:
:CALC{1-36}:PAR:COUN
Only the currently displayed traces can be active traces. Therefore, you must set the number of traces appropriately before making them active.
To select the measurement parameter (S parameter) for each trace, use the following command:
:CALC{1-36}:PAR{1-36}:DEF
When you use the Balance-Unbalance Conversion feature, you can select the mixed mode S parameter as well. For more information, refer to Analysis Using the Fixture Simulator.
How you can set the sweep condition depends on the sweep type. You can choose between the following four sweep types:
Linear sweep
Log sweep
Segment sweep
Power sweep
To select one of the above sweep types, use the following command:
:SENS{1-36}:SWE:TYPE
To select the sweep mode (stepped/swept), use the following command:
:SENS{1-36}:SWE:GEN
To turn on/off the stimulus signal output, use the following commands. For example, if the power output is automatically turned off due to the power trip feature, remove the cause of the over-input and turn on the stimulus signal output by executing the following command. You cannot perform measurement until you turn on the stimulus signal output.

To set the sweep range, use the following commands:
|
Type |
Command |
|
Start value |
:SENS{1-36}:FREQ:STAR |
|
Stop value |
:SENS{1-36}:FREQ:STOP |
|
Center value |
:SENS{1-36}:FREQ:CENT |
|
Span value |
:SENS{1-36}:FREQ:SPAN |
To set the number of measurement points, use the following command:
:SENS{1-36}:SWE:POIN
To set the sweep time, use the following commands:
|
Type |
Command |
|
Sweep time |
:SENS{1-36}:SWE:TIME |
|
Turning on/off auto setting |
:SENS{1-36}:SWE:TIME:AUTO |
To set the sweep delay time, use the following command:
:SENS{1-36}:SWE:DEL
To set the IF bandwidth, use the one of the following commands (both provide the same function):
:SENS{1-36}:BAND
:SENS{1-36}:BWID
To set the power level, use the following command:
:SOUR{1-36}:POW
To select whether to output the same power level (the set value for port 1) or a different power level for each port, use the following command:
:SOUR{1-36}:POW:PORT:COUP
:SOUR{1-36}:POW:PORT{1-4}
To set the correction of power-level attenuation so that it's proportional to the frequency (power slope feature), use the following command:
:SOUR{1-36}:POW:SLOP:STAT
:SOUR{1-36}:POW:SLOP
If you turn on the power slope feature, the sweep mode is changed to the step mode.
When you opt to use segment sweep, you can set all items (in the segment sweep table) by using a single command:
:SENS{1-36}:SEGM:DATA
Alternatively, you can configure the segment sweep settings based on the data contained in a CSV file by issuing the following command:
:MMEM:LOAD:SEGM
Also, you can save the contents of the current segment sweep table to a file by issuing the following command:
:MMEM:STOR:SEGM
For more information on how to save and load the segment sweep table, refer to Saving and recalling the segment sweep table.
To set the sweep range, use the following commands:
|
Type |
Command |
|
Start value |
:SOUR{1-36}:POW:STAR |
|
Stop value |
:SOUR{1-36}:POW:STOP |
|
Center value |
:SOUR{1-36}:POW:CENT |
|
Span value |
:SOUR{1-36}:POW:SPAN |
To set the fixed frequency (CW frequency), use the following command:
:SENS{1-36}:FREQ
To set the number of points, the sweep time, the sweep delay time, and the IF bandwidth, use the same commands as for the linear/log sweep.
To configure the averaging settings, use the following commands:
|
Type |
Command |
|
On/off |
:SENS{1-36}:AVER |
|
Averaging factor |
:SENS{1-36}:AVER:COUN |
|
Clear (Restart) |
:SENS{1-36}:AVER:CLE |
For averaging, normally, the instrument must be triggered according to the number of averaging; however, when the averaging trigger is turned on, sweeps for the number of averaging can be executed by a single trigger. For details on the averaging trigger, refer to Averaging Trigger Function.
This function is available with the Firmware revision 3.01 or greater.
To set the system characteristic impedance (Z0), use the following command:
:SENS:CORR:IMP
